PURPOSE:To decide on a damage state of a titled electric equipment due to an impact without opening its metallic container, by providing the metallic container of the electric equipment with an impact detector. CONSTITUTION:The metallic container 1 of the electric equipments consists of a weight part (a), necking part (b), support part (c), etc., and the impact detector 2 having nearly the same inherent oscillation frequency and strength as the electric equipment is provided. Therefore, a damage state of the electric equipment due to an impact during transportation, etc., is discriminated easily and accurately from the occurrence of variation in state due to a breakdown, etc., of the detector 2 without opening the container 1. |
